Line switches and line disconnects shall be located so that they are readily
accessible from climbing and working spaces. Such devices or their connecting
leads shall not extend into the climbing space but may extend into the working
space.A. Unenclosed

(1)
Vertical
clearances between exposed energized parts of line switches and line
disconnects (including fused and unfused line cutouts) and unprotected conductors
of other circuits above and below shall not be less than the clearances
specified by Table
2, Cases 8 to 13 .

Clearances between exposed parts of line switches and line disconnects
(including fused or unfused line cutouts) which are energized from the same
circuit, from exposed parts of different phases or polarities shall not be less
than the clearances specified by Table 2, Case 17 .

(2)
Lead
wires shall be suitably insulated from cases of cutouts and switches at points
of entrance thereto.

All unprotected lead wires including miscellaneous wiring shall clear braces,
bolts and other line hardware a distance of not less than 1.5”.

Where necessary at points of entrance to cutouts and switches, lead wires of 0
- 5,000 volts may be less than 3 inches from the surface of crossarms
(
Table 1, Case 9, Columns C, D and E
) but shall not be less than 1 inch from such surfaces.

(3)
Switches
and cutouts shall be so located that, when in either the open or closed
position, all energized parts thereof are not less than 15 or 18 inches from
the centerline of pole as required by Table 1, Case 8 , and no part of such equipment
shall be in the climbing space except nonmetallic interphase shafts of gang
operated switches and their associated unbonded
hardware mounted at the top of the pole (see Figures 58-2 and 58-3 ). Such apparatus is permitted to be
within the working space. The clearance of 15 or 18 inches need not apply to nonfusable pole–top switches provided the switches are
installed substantially in the same vertical plane as the conductors to which
they are attached, and no climbing space has to be provided through and above
the level of such switches.

(1)
Grounded
metal operating rods which pass through any supply or communication conductor level
shall be protected with a suitable protective covering for a vertical distance
of 8 feet above and below or 6 feet horizontally from such levels.
